T 0 all whom it may concern:

' Be it known that I, GEORGE W. MAXWELIL,

citizen of theUnited States, residing at San F ranclsco, 1n the countyof San Francisco- Containers, of which the following is a specification.

My invention relates to containing vessels or receptacles and moreparticularly to such dcvices as' are formed from fibrous material,

preferably paper, and it has for its object to provide a vessel of thischaracter that can be Y sealed and cheaply formed yet which will possessgreat ,thereby preserve its contents from'contamination. or decay.

An embodiment of the invention is shown in the acoompanyins drawingwhich shows a central 'longitudina section of the inven tion.

Referring more particularly to the drawing, 1 indicates the body of mycontaining vessel which'is preferably of tubular form be- 'ing shown inthe drawings as tho frustum of a cone. It is also preferably formed fromfibrous material, as a single sheet or thickness of paper in the form ofa segu'rent of an annular disk. in forming the body the blank is rolledinto tubular f rm with its edges overlapped, and hermetically joinedtogether, as by a line of glue or cement.

The bottom is permanen tly and preferably hermetieally secured to thelower orsmaller end when the vessel 1s formed, and the-top or cover istemporarily secured near the upper end when the vessel is filled.

The bottom is in the form of a disk as shown at 6, similar to the to 7,and inserted of the bottom being" 'orced back up into the 'largerdiameter ofthe body and thereby loosening the oint and rendering it morev liable to leak an d for the bottom to come out. The bottom is placedin position before the vessel is treated to a coating of liquid re--poll ng material, as by being dipped into melted paralhn, which rendersthe materlal of the vessel water proof and also hermetically closes thejoint between the bottom and the body, as-well as the edges of the seam"or joint from top to bottom of the body.

As above stated the top 7 is in the form of a flat disk of suflicientthickness to give the requisite strength and rigidity to hold thecontents against removal, even with rough usage,,,and its edge may beslightly beveled to more perfectly contact with the interior .of thebody when inserted for retainulg the contents. After the top has beeninserted to the required distance, which may be far enough lac-slightlybend or bulge out the side of the body as shown at 10, it is immovablysecured in place by a plurality of tongues or inwardly extendingprojections 11 which are formed by three incisions 12-, 12 and 13through thewall of the body, two at the sides of the tongue, preferablyparallel with each other, and one atthe bottom, which joins the othertwo. The bottom out or incision is at a slight distance below the planeof the top of the cover as shown at 14, whereby, when the tongue isforced in,

which is preferably done by machinery at the.

time the vessel. is filled, its lower edge will engage firmly with thecover and prevent any outward movement thereof, which mg 'a shallowrecess and thereby insures a perfect contact between the two throughoutthe thickness of the tongue.

As above described my containing vessel can be so cheaply formed that itcan be' thrown away aftononce using, thereby rendering it possible toprovide a receptacle for perishable products which is absolutely cleanand can be sterilized, as at the time of manufacture when it is dippedin heated paraffin for water proofing it. This renders it peculiarlyadapted for milk as it can be filled at the creamer-y or other milkdepot while the milk is pure and fresh and, as the vessel is made by antome-tie machinery, and sterilized as above described, there isabsolutely no chance for it to become contaminated except while beinghandled preparatory to filling, when extra precautions can be taken topreserve it in its purity and cleanliness. And as it is to be thrownaway, or not used, after having been emptied, its use saves all the costand waste of cle'aning'glass bottles besides avoiding the danger fromimperfect sizes, as I propose making three sizes for buler form cleaningand lack of sterilization as it is impossible to heat vesse to over 208degrees, the sterilizing point, Without taking afmucli longer time thanWill be given by the ordinary milk producer or dealer.

I. i is "i milk, itlie pint, half pint and. quart, (he filled vessel canbe dropped upon the iloor without breaking or spilling any of itscontents.
